We're dividing 3123418 by 521 
Our goal is to divide 3123418 by 521.

Advancing to step 1:
3 divided by 521 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 521

Advancing to step 2:
The number 521 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 521

Moving on to step 3:
521 can be fit into 312 0 times, resulting in a remainder of 312.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 312 after subtracting 0 from 312.
Bring next digit (3) of the dividend behind the 312 and repeat the process: 3123 / 521

Let's proceed to step 4:
521 can be fit into 3123 5 times, resulting in a remainder of 518.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 2605 from 3123 to get 518.
Include the next digit (4) from the dividend after 518, then repeat: 5184 / 521

On to step 5:
5184 divided by 521 is 9 with a remainder of 495.
The next digit of our result is 9. 
Result so far: 59.0
If we take 4689 away from 5184, we end up with 495.
Bring next digit (1) of the dividend behind the 495 and repeat the process: 4951 / 521

Step 6:
The number 521 fits into 4951 9 times, leaving a remainder of 262.
Record the quotient 9 as the next digit in the result. 
Result so far: 599.0
Deduct 4689 from 4951 and we're left with 262.
Include the next digit (8) from the dividend after 262, then repeat: 2628 / 521

Moving on to step 7:
2628 divided by 521 is 5 with a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 5995.0
If we subtract 2605 from 2628, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
230 divided by 521 is 0 with a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 5995.0
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
2300 divided by 521 is 4 with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 5995.04
Subtracting 2084 from 2300 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 10:
2160 divided by 521 is 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 5995.044
Deduct 2084 from 2160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 5995.044 with a remainder of 0.0076.
